Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and in particular to an integrated butterfly valve with an anti-clogging and easy-to-clean filter. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is characterized by a disc-shaped closing element that rotates around a valve shaft to open and close. The butterfly valve's opening and closing element is a disc-shaped plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation.

[0003] Butterfly valves are used in various fluid transport systems. When the fluid contains solid impurities (such as mud, rust, metal shavings, etc.), these impurities can easily enter the valve with the fluid because the internal structure of the butterfly valve is relatively simple and there is no filter device. The impurities accumulate in the sealing area between the valve disc and the valve body or around the valve seat. Once the butterfly valve is blocked, the effective flow area of ​​the fluid through the valve will be reduced, which will affect the progress of chemical reactions and product quality. In order to solve the above problems, we have proposed this anti-clogging, easy-to-clean butterfly valve with integrated filter. Utility Model Content

[0004] The main purpose of this utility model is to provide an integrated butterfly valve for anti-clogging and easy-to-clean filters, which can effectively solve the problems in the background art.

A drain pipe is connected to the lower end of the connecting pipe. A first valve is provided at the upper end of the drain pipe. A filter screen is installed on the inner wall of the connecting pipe through a mounting ring. A flushing mechanism for flushing impurities is provided on the connecting pipe.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-3As shown, the anti-clogging and easy-to-clean integrated butterfly valve with filter includes a butterfly valve body 1. A connecting pipe 2 is provided on the side wall of the butterfly valve body 1. An interception mechanism for intercepting impurities is provided inside the connecting pipe 2. The interception mechanism includes an installation cylinder 6 fixedly connected to the connecting pipe 2. A rotating rod 4 is rotatably connected inside the installation cylinder 6. A filter disc 5 is fixedly connected to the side wall of the rotating rod 4. The filter disc 5 can rotate inside the connecting pipe 2 and perform sealing. Its structural principle is the same as that of a butterfly valve. A limit groove is opened at the upper end of the rotating rod 4. A limit block 7 is provided in the limit groove. A limit cover 13 is provided at the upper end of the limit block 7. A drain pipe 3 is connected to the lower end of the connecting pipe 2. A first valve 9 is provided at the upper end of the drain pipe 3. A filter screen 12 is installed on the inner wall of the connecting pipe 2 through an installation ring 11.

[0021] The connecting pipe 2 is equipped with a flushing mechanism for flushing impurities. The flushing mechanism includes an injection pipe 8 installed on the connecting pipe 2, and a second valve 10 is installed on the injection pipe 8.

[0022] In this utility model, the mounting ring 11 is fixedly connected to the connecting pipe 2, and the mounting ring 11 is threadedly connected to the filter screen 12, which facilitates the disassembly and installation of the filter screen 12.

[0023] In this utility model, a rotating block is fixedly connected to the side wall of the filter screen 12 to facilitate the rotation of the filter screen 12, and the second valve 10 is a solenoid valve.

[0024] In this utility model, two observation ports are provided on the side wall of the connecting pipe 2, and an observation window 14 is provided in the observation port to facilitate observation of the filtration of impurities on the filter disc 5.
